Wash with a WOOL mitt, use a wax-based car shampoo, not dish soap. Dawn will cut all the wax off the paint.
Best drying chamois are those yellow synthetic ones from Germany - $20 for a pack of four. You can cut one in half it it's too large. Can get them here:

Armorall is an inferior product - try 303 Aerospace protectant instead. "40SPF for your stuff". Good for all rubber, vinyl, and plastic surfaces. Non-oily, non-shiny, deep color. Comes from the marine and aircraft industries. You'll thank me later.
And my favorite glass cleaner, tint or no, is Sprayaway. Can get it at any big-box store, wallyfart, HD, etc. Low-lint paper towel works great - my favorite is Brawny. Most other brands are inferior and leave a lot of paper lint.
Your car can always look like new.
